PECIFICATION formnglpart of Letters Patent No. 534,076, dated February12, 1895.

Application iiledNOvember 17, 1894- Serial No. 529.133. (No model.)

To @ZZ whom, it may concern:

ing to be a full, clear, and exact description of the invention, such aswill enable others skilled in the"art to which it appertains to makeand-use the same.

My invention relates to improvements in the rods used on rolling slatwindow blinds; and the objects of my improvement are, first, to providea metallic rod of a simple and cheap construction the rod having slotswith bridges formed between them thereby dispensing with the staples nowin use in wooden rods making a more durable and permanent construction;second, to provide a metallic rod having bridges formed between slots,the bridges in the rod connected to the slats of a window blind by screweyes, the bridges and the screw eyes forming the pivots to operate theslats; third, to provide metallic rods for rolling slat window blinds,the rods attached to the blind slats by screw eyes and. having springsat their upper ends to close the slats when the rodsare disengaged fromthe holding pin attached to the blind frame. I attain these objects bythe device and arrangement of the parts illustrated in the accompanyingdrawings, in Which Figure 1, is a vertical front view of a window blindhaving my improved rod attached. Fig. 2, is a vertical side view of thesame. Fig. 3, is an enlarged detail front View of a part of my improvedmetallic rod. Fig. 4,- is an enlarged detail sectional view through thecenter of the slats, showing the screw eyes attaching the rod to theslats. Fig. 5, is a detail front view of the same.

Similar letters refer to similar parts throughout the several views.

The blind Arepresents the usual form of a framed blind as used onwindows. The blind frame is provided with a series of slats B, the slatshaving pivots formed on their ends operating in the frame in the usualmanner, to open or close the slats as may be desired, the slatsbeing-operated bya rod attached to the slats in a suitable manner.

The operating rod C is made of any snitable flat metallic material. Aseries of slots D is formed in the center of the rod, a series ofbridges E being left between the slots. The slots are preferably formedwith the ends of the slots circular as shown. The rod can be formed as achannel bar if desired with the edges turned up to give it stiffness.The lower end of the rod is curved to form a handle to operate the rod.A knob-or other form of handle can be used if desired.

A series of screw eyes F is inserted in the blindV slats. Beforeinsertion in the slats the eyes are opened a sufficient amount to allowthe bridges of the metallic rod to enter the eyes. When the bridges ofthe rod are hooked in the eyes, the eyes are closed to engage thebridges as shown.

A coiled spring G is attached to the rod at the upper end. The remainingend lof the spring is secured in any suitable manner to the blind frame.A pin or hook H is attached to the bottom of the blind frame. The rod isprovided with one or more holes J to engage the rod by hooking it on thepin. To open the slats the rod is drawn down and hooked over the pin atthe place desired. The rod when unhooked is drawn up by the spring toclose the slats.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

l. In a blindslat rod, the combination with the blind slats of ametallic rod the rod having a series of longitudinal slots formed thereytween the slots, e series of screwfeyes inserted In testimony whereof Iex my signature in the blind slats Vthe eyes standing ab right inpresence of two witnesses. angles to the slats and engaging the barsformed in the rod, a spring connecting the upper end of the rod to theblind frame, two holes provided in the lower end of the rod to engage a.pin attached to the blind frame, substentielly as and for the purposeset forth.
